We are constantly exposed to some level of radiation on a normal basis. It is a natural part of our planet. That natural radiation becomes ionized by the ground, outer space, and even human bodies. Therefore, we breathe it in the air, eat it in our foods and drink it in our water. Even our homes contain these low levels of radiation due to the building materials.

As the population continues to grow, so does the demand for food. In the US alone, food consumption is projected to increase by as much as 20% by the year 2020. So the big question now is where do we get all of this food to feed the masses?

Water is one of our most valuable resources. Studies have shown that a person can survive for several days without food, living on water alone. Our body's  are mainly composed of water, which we utilize and therefore must replenish. However, before you drink that clear crystalline tap water, consider if it’s safe?

In 1908, an amazing invention was created in the United States: the Ford Model T. With the development of such a useful and convenient product it was no surprise that demand soared. By 1914, the Ford company had invented the assembly line to increase production and meet demand. Nearly 40 years later, the US Environmental Protection Agency became aware that our clean air needed protection.

Let’s face it; we live in a polluted environment. Groundwater becomes contaminated when man-made by-products mix with the water supply. These products include gasoline, oil, road salts, and heavy metals. They come from septic systems, storage tanks, landfills, fertilized fields, highway runoff and the list goes on and on. Once these pollutants mix with groundwater, it is no longer fit for direct consumption without additional treatment.

One of the most inflated commodities is water, even though it’s the most abundant resource on earth. Water covers ¾ of the earth’s surface but has somehow become very costly. What used to be free, now commands a price. One can no longer drink the water coming from faucets, unless it is purified. Gone are the days when you can savor fresh and totally natural water from streams and rivers. Indeed, water pollution has overtaken this age.

Can you imagine life without batteries? Batteries of various types and voltages are found in almost all portable gadgets today. While they may bring life these gadgets, they cause deterioration and pollution of the environment when not properly disposed. The choice is in your hands, in fact only you have the power to properly dispose of your batteries (pardon the pun).

Climate change happens when certain elements in the atmosphere allow sunlight to pass freely, yet trap the light that is reflected back. Light enters the earth freely, but instead of leaving the atmosphere after reflecting off the ground, it gets trapped and the earth just keeps on getting warmer and warmer.

The standard chlorine bleach that you normally find in any supermarket or drugstore has a 5.25% sodium hypochlorite content. This chemical is a very effective whitener. It can remove stains, disinfect and whiten clothes. While this chemical can be very good for cleaning, there are also some serious health hazards to consider.

Everybody wants to live a long healthy life. People look for products that can bring them more protection from germs, bacteria, and other health-adverse microorganisms. As an answer to this consumer demand, manufacturers started producing antibacterial soaps and disinfectants. These products have become fairly popular since killing bacteria and disinfecting germs sound like a good idea.
